Need Help with calculating load for my transfer switch

Hey All...

Now that I fixed my transfer switch mounting issues, its time to select which circuits I want to run while on gen power.

The switch have is..

My generator is a 120 volt only. With 25 amps rated, and max 30.

I would like to run the following with the gen, now obviously since I have a smaller genset I know I cant run it all at once.

Stuff that would be on all the time...

Tankless Water Heater (uses about 50 watts)
Security Alarm Pnl (not sure of watts)
Fridge (2 year old energy efficient LG fridge)
Furnace Blower (seasonally, small 2 ton unit)
Lighting for a few rooms (recessed LED light) All light bulbs in my house are either led or cfl.

Stuff that would be intermitant use.
2 LED TV / DVD / 2 TIVOs
Microwave
Bath Room Outlet (wifes hairdryer)

Would this be too much to run on this switch ?

The main CB on the switch that connects to the main panel is a 60 amp CB. Really my question would be is that too much load to be in the panel for regular everyday utility power use?

You are fine except for the hot water. No hot water heater on earth could be 50watts. Are you talking about a gas heater with an igniter or something? If so, then no biggie. The dryer will probably kick you out if he furnace and fridge are cycled on but.....
Otherwise it looks totally doable.

Hey Volvo...

Thanks for the relpy.

The water heater is a gas fired tankless Navien unit.

I guess it uses electric for the ignition, blow fan for exhaust, and the heating element that keeps the copper inside from freezing, since its in my attic.

Without juice it produces no hot water
